本文仅就响应矩阵法中引起误差的主要因素进行研究,从而给出误差的定量评价。结果表明:编制响应矩阵时,使用矩形康普顿谱形时,对照射量率的评价偏高,其最大值为10％,而使用Berger和作者实测的康普顿谱形时,评价很接近,分辨率对照射量率的变化<±2％;响应矩阵的能量范围对照射量率的变化<-2％,增益变化±10％时对照射量率的变化<±1％;零点漂移±10道址时照射量率的变化<±32％
In this paper, only the main factors that cause errors in response matrix method are studied, and the quantitative evaluation of errors is given. The results show that when using the Compton-Rectangular Rectangular Rectangular Matrix, the evaluation of the radiation rate is very high with a maximum value of 10%. When using the Compton spectrum measured by Berger and the author, the evaluation is very close , The variation of the resolution relative to the measurement rate is <± 2%; the range of the energy of the response matrix is less than -2% of the irradiation rate and the variation of the irradiation rate <± 1% when the gain is changed by ± 10%; the zero drift ± 10 Road site when the amount of exposure rate changes <± 32%
